Model Dependencies

[onwardmk]

We are exclusively using FHIR version R4, and I would like a way to not require the DSTU2 and STU3 model packages, as they take up about 40 MiB. Is it possible to split up the client and models into separate gems, so that they can be installed separately, or will this break code in the client? I'm hoping there's a way to do this without forking the repo.

I'd like to suggest excluding the examples directory in each of the model gems because I think these are only for documentation and they take up a significant amount of space.

Could we add this to the .gemspec for each of them:

spec.files = Dir.glob("**/*") - Dir.glob("**/examples/**/*")
